How to use PHP to implement picture scrolling operation in WeChat applet

With the widespread use of WeChat mini programs, more and more developers are beginning to use PHP to implement various functions. Among them, picture scrolling is a common operation in WeChat mini programs. Here is an introduction to how to use PHP to implement picture scrolling operations in WeChat mini programs.

1. Preparation work

Before we start, we need to prepare the following things:

• A development environment for WeChat applet;
• A server environment that can run PHP;
• A set of pictures that need to achieve the picture scrolling effect.

2. Write PHP code

First, we need to write code in PHP to read and load the images that need to achieve the scrolling effect. You can use the glob function in PHP to obtain all image files under the specified path, and then use a loop statement to load these images into the applet. The specific code is as follows:

$images = glob('/path/to/images/*.{jpg,png,gif}', GLOB_BRACE);
foreach($images as $image){

//加载图片到小程序中

}

Next, we need to create a scrolling window for these pictures so that the user can browse these pictures through swiping gestures. You can use the echo function in PHP to output HTML and CSS code to create a scrollable window for these images. The specific code is as follows:

echo '

';
foreach($images as $image){

echo '<div><img  src="/static/imghwm/default1.png"  data-src="'.$image.'"  class="lazy".$image.'" alt="How to use PHP to implement picture scrolling operation in WeChat applet" ></div>';

}
echo '

';

3. Write CSS code

Next, we need to write code in CSS to implement the style of this rolling window. The code is as follows:

.scroll-container {

display: flex;
overflow-x: scroll;
scrollbar-width: none;

}
.scroll-container::-webkit-scrollbar {

display: none;

}

Just copy and paste the above code into the style file.

4. Complete

Now, we have successfully used PHP to implement the image scrolling operation in the WeChat applet. Users can browse these images with swipe gestures, and the entire operation is very smooth and easy to use.
